Filthstep is an especially abrasive, high-impact strain of dubstep that emphasizes snarling mid‑range basses, extreme distortion, and hyperactive modulation. Sitting between UK dubstep’s half‑time lurch and the North American “brostep” festival push, filthstep typically runs at 140 BPM, using half‑time drum grids, machine‑gun bass phrases, metallic FM growls, screeching reese variations, and aggressive edits. Sound design is the star: producers sculpt layered wavetables and resampled bass hits through OTT compression, waveshaping, comb filtering, and rapid LFO automation to achieve a deliberately “dirty” or “filthy” texture. While often used informally as a scene term, filthstep marks a recognizable aesthetic—maximalist drops, call‑and‑response bass riffs, cinematic/horror stabs, and crowd‑igniting switch‑ups—optimized for club systems and large festival rigs.

Jump up is a high-energy, dancefloor-focused subgenre of drum and bass characterized by bouncy, instantly memorable bass riffs, playful samples, and a party-first attitude. It typically runs around 170–176 BPM, with crisp two-step drum patterns, punchy snares, and simple, hook-led midrange “wobble” basslines that cut through club systems. Aesthetically it leans toward bright, cheeky motifs—brass stabs, hip‑hop or dancehall MC phrases, and call‑and‑response bass hooks—designed for rewinds, double drops, and big crowd reactions. While rooted in jungle’s breakbeats and sound system culture, jump up pares back complexity for maximum bounce and impact, prioritizing groove, movement, and memorable motifs over intricate harmony.
